● Implemented the use of Java Mailing or Messaging Service (JMS) API's for mailing detailed notifications depending upon the success and failure once the backend process is complete and for mailing administrator of any system related problems.● Configured Spark Streaming to receive real time data from the Apache Kafka and store the stream data to HDFS using Scala and utilizing Data frames and Spark SQL API for faster processing of data.● Implemented Spring MVC to achieve Model View Controller design pattern and configured spring to manage actions as beans and set their dependencies in a spring context file and integrated middle tire with spring web layer.● Created scalable and efficient data pipelines using AWS services and Java programming language and designed efficient schemas for data warehousing purposes and developed ETL processes to extract, transform, and load data into target systems using Java-based frameworks and libraries.● Worked upon Data Extraction and aggregations for AWS Glue to crawl the data lake in S3 to populate the Data Catalog and also developed data ingestion modules using AWS Step Functions, AWS Glue and Python modules.● Exported SQL data into Elastic search to allow faster and scalable user searches from the database and developed Soap and Rest web services. Implemented spark solution to enable real time report from Cassandra data.● Created SQL queries and executed them by using Hibernate Template provided by spring for improving the performance of the Reporting modules. Developed GUI using AngularJS, curated changes for client validations using JSP, HTML.● Used modern data analytics and visualization tools including elastic search and kibana to build efficient application metrics monitors.● Developed Java API to connect with AWS S3 Services for storing and retrieving data stored in the S3 buckets and made use of AWS SDK to connect with Amazon SQS for bulk email processing.

● Amazon S3 was used as object storage service to store and retrieve media files such as images and Amazon Cloud Watch was used to monitor the application and to store the logging information.● Implemented Micro Service Architecture with Spring Boot based RESTful services and consumed SOAP based Web Services.Loaded the data into Cassandra Cluster with the help of Java API.● Involved in deploying web applications through Beanstalk Elastic Load Balancing for high durability of the application and was also involved in writing java API for Amazon Lambda to manage some of the AWS services.● Wrote AWS Terraform templates for the required automation in AWS services and created database objects in AWS Redshift and also implemented Router Module from Angular to comprise the project into a single page application.● Closely worked with Kafka Admin team to set up Kafka cluster setup on the QA and Production environment and Has knowledge on Kibana and Elastic search to identify the Kafka message failure scenarios.● Designed, implemented, and deployed J2EE web application using Spring MVC and Hibernate and developed persistence layer using Spring JDBC template and Hibernate Template.● Involved in the development of Enterprise Java Beans (EJB) to implement Business logic for maintaining state information and database operations. Also majorly involved in the migration process to Java 1.8 from java 1.6 and updating several dependencies such as hibernate, spring.● Modeled JSON data from database and coded request handlers for parsing and sending relevant data to browser and developed web services using JAX-WS to interact with application’s backend processes.● Developed technical design documents and created a prototype of the business application using JAVA/J2EE and Initiated use of Unit for testing.

● Involved in the implementation of SQL to execute queries on data persisting in the Cassandra cluster and developed front end using the JSF, XML, HTML5, CSS3, JavaScript, JQuery and AngularJS. ● Worked on Amazon Web Services (AWS) infrastructure with automation and configuration management tools such as Chef and Puppet.● Involved in writing shell scripts to export oracle table\'s data into flat files and performed unit testing using JUNIT and used Log4j for logging and automatic batch jobs.● Utilized Groovy along with Java for developing the Microservices required for the project. Confluence was used as a tool to keep the project progress in check.● Created a digital framework and planned all the steps required for completing the project parts in separate phases following the Agile Methodology.● Designed Data Marts by following Star Schema and Snowflake Schema Methodology, using Data Modelling tools like Erwin.● Written Terraform modules for automating the creation of VPC's and AWS EC2 Instances, modules for creation of VPC and VPN connection from Data Center to production environment.
